Thermal constriction resistance of arbitrary planar contacts with constant flux
Abstract
An integralnumerical method is used to determine the temperature field and the steadystate thermal constriction resistance of singly connected planar contact areas of arbitrary shape with constant flux on insulated halfspaces. An alternate definition of the constriction resistance based upon the centroidal temperature which is easily computed resulted in a dimensionless resistance which is rather insensitive to the shape of the contact and its aspect ratio. Most contact geometries can be modeled as circular contacts having the same area with an error not exceeding 5%.
